Thalassemia is inherited, meaning that at least one
of your parents must be a carrier of the disease.
It’s caused by either a genetic mutation or a deletion
of certain key gene fragments.
Thalassemia minor is a less serious form of the disorder.
There are two main forms of thalassemia that are more serious.
In alpha thalassemia, at least one of the alpha globin genes has
a mutation or abnormality. In beta thalassemia, the beta globin
genes are affected.
Each of these forms of thalassemia has different sub-types.
The exact form you have will affect the severity of your symptoms and your outlook.
